Seeking closure! Was this issue resolved? Pi Zero / Adafruit / Audio issues

[Martina285491]

Hi All

Poor sound quality and cracking with pi zero

Poor sound quality and cracking noise coming from pi zero running 2.5w d class adafruit amp and a 3w 4ohm 1.5” speaker running through one of the gpio pins. I have tried different amps and boards but nothing changes, is there a way I can increase the audio quality and remove that cracking sound?

So this is from March 2024, involving the wonderful individuals

I’m currently experiencing the exact same issue, with, no surprise, the exact same project.

There’s a lot of useful info and a bunch of fixes I will try, but can anyone tell me if this was actually resolved?

Thanks so much to everyone involved!

Hey Martina.
From we never got the confirmation from the user.
Even so, Jeff and Rob’s suggestion are just good practice and you should consider implementing them anyway. Particularly looking over MCU frequencies.

If you don’t find joy , post a picture of your setup (and a schematic if possible) I’m sure the community won’t mind a revisit.
